Hmmm, maybe should have no prompt and 'depends on RC_ONCE' (instead of
selecting it above). I don't think there is a use-case for not persisting
the machine-id if rc-once is available.
This is different from the ssh server key case: There are other ways to
create the keys.

Maybe install_alternative and an empty on in projectroot/. Sometimes it's
better to share the same machine-id across devices than having a new one
after rebooting.
Also, this should only happen for !PTXCONF_MACHINE_ID_RC_ONCE. It's not a
good idea to modify files that are installed by a package.

So this is still needed inside the 'if'.

Why should one select rc-once, if it is not needed by any other package? Maybe make it even invisible?
In my projects I use an initramfs where I mount an overlayfs over /etc. When systemd starts /etc/mancine-id is writable while / is never mounted rw.
So I want just to install an empty /etc/machine-id and let systemd generate and write the new one. rc-once just jeopardize this.

Good idea. I'll change this.

This is the case for almost all files in /etc if they are modified on the target. I avoid it with the overlayfs. In this way defaults are installed by the packages and changes are stored on the target.

I moved it into the package because otherwise an empty package is not generated.
ERROR: no files installed
With this patch machine-id would be reset on reinstall, but why should someone reinstall the machine-id package?

Well, one of my systems has a service for that. Machine-id is generated using
hardware info. In that case I do not mind as RC_ONCE is not selected, but there
is a use-case in general. However it is still possible to override
rules/machine-id.in in BSP, so...

There are other ways to create machine-id too...

I'm ok with keeping the prompt for MACHINE_ID_RC_ONCE, but you have ignored
all my other review as well. That still needs to be fixed.
